DETAILED DESCRIPTION

Detailed descriptions of one or more preferred embodiments are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in any appropriate system, structure or manner.

It is to be understood that the marking apparatus 100 is applicable to any marking or punching use.

Force Bar with Positioning Member

FIG. 1 shows perspective view marking apparatus 100 with force bar 300 and handle (handle 200 can be the length of arm 300 following angle 370), and positioning member 500.

In this embodiment positioning member 500 can include marking point 550 on bottom side and rounded positioning member on top 520, with positioning member 500 having two longitudinal grooves (600, 610) and threads 515 close to marking point 550.

FIG. 1A shows a view taken from the lines A-A of FIG. 1 of the marking point 550 of positioning member 500.

FIG. 1B is a perspective view of positioning member 500 where positioning member 500 has been rotated 90 degrees relative to the position shown in FIG. 1. Positioning member is shown rotated to better illustrate the double grooves 600 and 610 (which can be seen in FIG. 1A, but not in FIG. 1). In FIG. 1B neither groove (600 or 610) lines up with notch 360 of arm 300. However, preferably during use either groove 600 or 610 will be lined up with notch 360 (as shown if FIGS. 1 and 1A).

In one embodiment marking device 100 can comprises a handle 200 (handle 200 can be the length of arm 300 following angle 370), arm 300, positioning member 500, and marking point 550. In embodiment positioning member 500 can be detachably connectable to arm 300.

In one embodiment marking point 550 can include a releasable marking substance such as paint, ink, dye, lead, graphite, and/or wax to increase the visibility of the mark left by marking point 550. In one embodiment marking point 550 can be similar to the point of a ball point ink pen, or a felt tip pen.

Arm 300 can include first end 310 and second end 320. Positioning 500 member can be detachably connected to second end 320. In a preferred embodiment positioning member 500 and marking point 550 can be longitudinally aligned with each other (and can be constructed from a single material).

Although not shown in the drawings, handle 200 can be non-parallel to and pivotally attached to first end 310.

On second end 320 of arm 300 can be opening 350 which can includes threaded area 355. In one embodiment opening 350 can include notch 360. First and second ends 310,320 of arm 300 can be rounded, flat, or angled.

Arm 300 (although illustrated as being generally rectangular) can be made in other shapes such as rounded, triangular, or other geometric cross sections which provide sufficient strength for the type of use contemplated, and can fit between the gap of a door and door jam.

Positioning member 500 can include first end 510, second end 520, and have a length “L”. In a preferred embodiment first end 510 can be rounded, hemispherically shaped, curved, and/or pointed to allow for easy insertion into an opening. Second end 520 can include a pointed area 550 which can act as punch 700. In a preferred embodiment, positioning member 500 is symmetrically shaped with pointed area 550 being located in the longitudinal center line 555.

In one embodiment positioning member 500 can include threaded area 515 which threadably attaches to a threaded area 355 (of opening 350) of arm 300.

In various embodiments positioning member 500 can be attached to arm 300 by threading, wedging, or other attachment techniques. By making positioning member 500 detachably connectable to arm 300, it is possible to replace positioning member 500 easily as this is the primary point of wear on apparatus 100.

Positioning Member Itself without and with Pull Cord

FIG. 2 shows perspective view of positioning member 500 with marking point 550. FIG. 3 shows perspective view of positioning member 500 with marking point 550 and force application member 900.

In one embodiment positioning member 500 can include one or more longitudinal grooves 600, 610, and/or 620 (although groove 620 is not shown in the drawings) about its positioning surface 530. In one embodiment one groove 600 is provided. In one embodiment two grooves 600 and 610 are provided which are symmetrically spaced apart 180 degrees from each other. Although not shown in the drawings, in one embodiment three grooves 600, 610, and 620 are provided which are symmetrically spaced apart 120 degrees from each other.

FIG. 1A is a view of one embodiment of a positioning member 500 with marking point 550, with the positioning member having two longitudinal grooves 600 and 610 symmetrically spaced apart (180 degrees from each other). Grooves 600 and 610 allow for increased adjustability of marking point 550 related to top 302 of arm 300 as only one groove need be lined up with notch 360. With only single groove 600 positioning member 550 must be turned at least 360 degrees before groove 600 will line up with notch 360. With two vertical slots 600 and 610 positioning member 550 need only be turned 180 degrees before one of the two notched line up with groove 360. FIGS. 1, 1A, and 1B show relative positions of grooves 600 and 610 to notch 360.

Alarm Sensor Installation

The use of apparatus 100 for installing door alarm sensors is schematically illustrated in FIGS. 3-10.

FIG. 4 shows marking apparatus 100 with handle 300 being placed in alarm sensor hole 2020 of top door frame 2010 with alarm sensor wire 20 hanging down, and with door 2500 open. The header of door frame 2100 can have opening 2020 in the header which had been previously made (such as by a drill) a sensor wire 20 hanging from the opening 2020. Although not shown, header can have both a front and rear portion with a door jam towards the rear and weather stripping placed on the door jam.

Door frame 2000 can have a door sensor system 10 which includes contact wire 20 along with upper 12 and lower sensor 14 elements. Door sensor system 10 (which includes upper sensor 12 and sensor wire 20) can be installed in the upper portion of a door frame 2000 (see FIG. 10).

In FIG. 4 the sensor wire 20 has been placed in the groove 600 of positioning member 500 of apparatus 100. The vertical groove 600 and wire 20 face the rear of the door frame 2000. Positioning member 500 is preferably about the same size as the opening 2020 in the header 2010.

FIG. 5 shows positioning member 500 of marking apparatus 100 now placed in alarm sensor hole 2020 with alarm sensor wire 20 hanging down, and with door 2500 open. After positioning member 500 is placed in opening 2020 of header 2010, wire 20 still hangs down from opening 2020 but is located towards the rear of the header 2010 (schematically indicated by the arrow 21). Marking point 550 is now located about in the longitudinal center of opening 2020 for header 2010.

FIG. 6 shows door 2500 in closed state and force (schematically indicated by arrow 2070) being applied on marking apparatus 100 with handle 300 while positioning member 500 is in hole 2020 of top door frame 2010 with alarm sensor wire 20 hanging down on other side of door 2500, and with door 2500 closed. Arm is located in gap 2050 between door 2500 and frame 2010. Preferably door 2500 is closed with door hardware (e.g., door knob 2504 ans strike plate 2200) on the door 2500/frame 2000 so that the door 2500 will lock in place in the strike plate 2200 (as the door will normally be used). When closed arm 300 of apparatus 100 can fit within the gap 2050 between the top 2510 of the door 2500 and the header 2010 of the door frame 2000. The hanging wire 20 also fits between the top 2510 of the door 2500 and the header 2010 of the door frame 2000 (on the top of the door) and between the rear of the door 2500 and the weather stripping 2004 in front of the jam 2006 (although not shown but located at the rear of the door 2500). Arrows 2072 schematically indicate that, in one embodiment, arm 300 can be pivoted somewhat about opening 2020 in header 2010 even when door 2500 is closed in door frame 2000.

FIG. 7 shows a section view of marking apparatus 100 with door 2500 closed and force (schematically indicated by arrow 2070) being applied on marking apparatus 100 with handle 300 while positioning member 500 is in hole 2020 of top door frame 2010 with alarm sensor wire 20 hanging down on other side of door 2500, and with door 2500 closed. Positioning surface 530 of positioning member 500 aligns positioning member 500 in the centerline CL of opening 2020 made in header 2010 of frame 2000. Marking point 550 can also being in the longitudinal centerline CL of positioning member 500 causing point 550 to be so aligned with centerline CL. When door 2500 is closed in frame 2000, pushing down on arm 300 (schematically indicated by arrow 2070) of apparatus 100 (shown in FIG. 39) causes point 550′ to create a mark 2550 in door 2500. In this manner, when door 2500 is closed, mark 2550 is also aligned with centerline CL of opening 2020.

As shown in FIG. 7, wire 20 does not interfere with alignment of positioning member 500 because wire 20 can fit in groove 600 while positioning surface 530 aligns positioning member in opening 2020. Also shown in FIG. 7 arm 300 and marking point 550 of marking apparatus 100 can fit within gap 2050 between top 2510 of door 2500 and header 2010 of frame 2000. In some instances the distance between first end 510 of positioning member from bottom 304 of arm can be adjusted upwardly in the direction of arrow 502 (or downwardly in the direction of arrow 504) by rotating positioning member in the direction of arrow 526 (or the opposite direction of arrow 526). As shown in Figure marking point 550 of positioning member 500 is generally located in the longitudinal centerline of opening 2020.

FIGS. 6 and 7 schematically indicate that force in the direction of arrow 2070 is applied downwardly to the top of apparatus 100 causing marking point 550 to make a mark, indentation, scratch or scar 2550 on the top 2510 of the door 2500. To better assist in seeing the mark, indentation, scratch, or scar a different material 2700 can be placed on the top of the door 2500 (such as painter's tape or masking tape). During this step the front portion 310 of arm 300 is generally in a horizontal position and located in a horizontal plane between gape 2050.

FIG. 8 shows a point mark 2550 placed on top 2510 of door 2500, and on or through marking material 2700. Generally, two types of marks 2550 which can be left by marking point 550 (either a point mark or a scratch line). Point mark is shown, however, although not shown a scratch line 2560 ending in a point 2550 can be made where marking point 550 touches the top 2510 of the door 2500 when the door 2500 is being closed. This can occur when there is only a small gap 2050 between the top 2510 of the door and the header 2010 (i.e., the bottom of the door frame).

FIG. 8 shows a mark 2550 which can be left by marking point 550 when using tape 2700. In another embodiment tape 2700 can be omitted. Painter's tape 2700 can be used to better show the mark 2550 made by marking point 550 (shown in FIG. 7).

After mark 2550 is made in the top 2510 of door 2500, marking apparatus 100 can be removed (substantially the opposite procedure is used as that schematically shown in FIG. 6). A user pushes up (in the opposite direction of arrow 2070) on the bottom 304 of arm 300 and opens door 2500. Door 2500 can be opened and marking apparatus 100 pulled down from out of opening 2020 of header 2010 (substantially the opposite procedure as shown in FIG. 4). The user pulls out positioning member 500 from opening 2020 in the header 2010. Wire 20 will then be left hanging from opening 2020.

In one embodiment (shown in FIG. 1) the positioning member 500 is vertically adjustable relative to the arm 300 to address the situation where there are small gaps 2050 and minimize scarring or scratch lines 2560. To vertically adjust positioning member 500, positioning member 500 can be partially screwed into or unscrewed from arm 300, where threads 515 of positioning member 500 will move positioning member 500 up or down relative to arm 300.

FIG. 9 shows a 2550 hole being drilled on top 2510 of door 2500 at mark 2550 and alarm sensor 14 being placed in the drilled hole 2555. The hole 2555 should be the size of the lower sensor 14 to be placed in the door 2510 and should be drilled parallel to a vertical plane passing through the mark 2550 on the top 2510 of the door 2500. FIG. 9 shows the hole 2550 being drilled through the painter's tape 2700. After the hole 2550 is drilled the painter's tape 2700 should be removed from door 2500.
